Elements of Blood
Elements of BloodBlood consists of 40 to 45% formed elements. Those formed elements include red blood cells or erythrocytes, white blood cells or leukocytes, and platelets or thrombocytes. Erythrocytes are those cells involved primarily in the transport of oxygen and carbon dioxide. Leukocytes are cells involved primarily in phagocytosis and immune responses. Thrombocytes are involved in blood clotting.In addition to the formed elements in blood, 55 to 60% of blood by volume consists of plasma. Plasma is a transparent, amber-colored liquid in which the cellular components of blood are suspended. It also contains constituents such as proteins, electrolytes, hormones, and nutrients. Serum is blood plasma from which clotting factors have been removed.
